佐藤式彎曲型咽喉頭直達鏡にて摘出した下咽頭食道異物の3例

抄録

There are many cases of foreign bodies in the hypopharynx or esophagus that are removed using a flexible fiberoptic upper gastrointestinal endoscope, however, there are also cases in which, due to the shape and size of the foreign body and/or the anatomical problems, it is difficult to remove foreign bodies using a flexible fiberoptic endoscope. Conventional rigid esophagoscopy can sometimes be difficult due to the problem of a narrow visual field. In these case, the Sato rigid curved laryngoscope strongly lifts the larynx and provides a wide field of view and space at the entrance of the esophagus from the hypopharynx.

Herein, we report three cases in which removal of a foreign body could be safely performed using the Sato rigid curved laryngoscope under general anesthesia.

The Sato rigid curved laryngoscope is a useful device to safely observe and remove foreign bodies, as a large working space can be secured due to expansion of the lumen of the hypopharynx and cervical esophagus.
